EQQ_Q04

EQQ - embedded query language query (event Q04)

4 segments

This query provides an envelope with which a query expressed in a language (e.g., SQL) is packaged and sent to the responding system. It is meant to provide the maximum query function without reinventing the wheel.

The EQQ with its EQL query defining segment supports free-form select statements, based on the query language of choice (e.g., SQL).
